To all whom itmag concern:

'Beit known that I, JOHNGF. COUGHLIiI,

.a citizen of the United States of America,

and a resident of Dorchester, inthecounty ofSufiolk and State of Massachusetts, have inventedcertain new and useful. Improvements in Toggles, ofwhich the following is a specification. V

This invention relates to devices for stretching leather, which are generally known as tanners toggles, and has for its object the production of a device ofthis class which will firmly grip the leather to be operated upon, which may be cheaply constructed, and will protect the operatlng parts thereof from the liquid used 1n fin: ishing the stretched leather.

The invention consists in certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims hereinafter given. 7

Of the drawings: Figure 1 represents a plan of a toggle embodying the principles of the present invention. Fig. 2 represents an inverted plan of the same. Flg. 3 represents a similar view showing the pulling cord attached thereto. Fig. t represents a longitudinal section of the same, the cutting plane being on line 4.4 on Fig. 1, and Fig. 5 represents a transverse section of the same, the cutting plane being on line 55 on Fig. 1.

Similar characters designate like parts throughout the several figures of the drawm s.

Tn the drawings, 10 is a member provided with an inturned end 11 unyieldingly positioned at an acute angle to the body portion. The opposite end is provided with a lip 12 bent over parallel to the body portion of the member 10, said lip 12 being adapted to be clamped upon the end of a spring member 13, the opposite end of which 00- 'acts with the inner face of the inturned end Patented A g. 17, 1915.

Application'filed April 11, 1914; Serial No. 8313681.

' conditions between saidinturned endrand the body portion of the member 10. The member 13 is provided with two flanges 15 straddling; the body portion of the member 10and extending from the bending point of saidmember to its free end, these flanges servingtwo purposes, namely, to register thespring member 13 and prevent lateral movement thereof relative to the member 10 and alsoitoprevent the material being used upon the leather 1% from getting between the two members 10 and 13 and clogging the same. These flanges, furthermore, make the member 13 so stiff and rigid between its free end and its bending point that the buckling of said member is absolutely pre vented. The point at which said member will bend is adjacent the point at which it is secured to the member 10.

As an additional safeguard to prevent the lateral displacement of the member 13, the lip 12 is provided with downwardly extending ears 16 which abut the side edges of the spring member 13 where it is clamped between the lip 12 and that portion of the member 10 opposite and parallel thereto. By this construction the movable member 13 is positioned relative to the member 10 without additional securing means, such as rivets, eyelets, etc. The member 10 is also provided with two securing fingers 17 and 18, both struck up from said member 10, the former extending longitudinally of said member 10, while the latter is perpendicular thereto, as indicated in Figs. 2 and 3 of the drawings.

The pulling cord 19 is secured to the toggle by laying the end 20 thereof upon the lower face of the member 10 and then forming a loop 21 around the projecting finger 17, then returning the standing part of the cord 19 over the end 20 and passing it beneath the finger 18, said fingers 1718 being both so constructed as to bite upon the cord 19 when it is pulled taut. The cord is quickly secured'to the toggle in this manner and positively holds the same without any danger of slipping.

The usual tying of knots is dispensed with when this construction is used, thereby making a great saving in the cost of labor, while the securing means is much more effective.

It will be observed that the upper face of the hide being treated is always above the upper portions of the gripping jaws and body portion of the spring member 13 and as a consequence the toggles are never in the Way during the treating operation. This makes a very eifective toggle which may be very cheaply constructed on account of the.

fully understood from the foregoing de scription.

- Having thus described my invention, I claim:

1. In a device of the class described, the combination of a member having one end bent at an acute angle and immovably positioned relatively thereto, and a spring member having sufficient stiffness to resist buckling secured thereto at one end and normally straight with its free end nearly perpendicular to and coacting with the inner face of said bent end to form gripping jaws, said spring member being adapted to be sprung inwardly for the insertion of material between the end of said spring member and the inner face of said bent end and to move outwardly toward its normal straight position to grip said material.

2. In a device of thecla'ss described, the

combination of a member having an unyielding end thereof inclined upwardly and toward the opposite end thereof and a spring member secured to said opposite end adapted to bend at a point adjacent these I JOHN G. CQUGrHLIN Boston;
